Wire tensioning device



Oct. 24, 1939. G. EGGINK WIRE TENSIONING DEVICE Filed April 14, 1958 Patented Oct. 24, 1939 UNITED STATES PATENT OFFiCE Application April 14, 1938, Serial No. 202,087 In the Netherlands April 22, 1937 1 Claim.

For the tensioning of wires, e. g., for making wire fences, it is already known to use a tool consisting of a bar, provided at one end with a cross bar and at the other end with a hook. In using 5 this tool an arbitrarily chosen point of the wire hanging slack between two fence posts to which it is fastened is passed about the cross bar, for which purpose the said cross bar may be provided With a hook if desired. The wire is then 10 wound about the said cross bar by swinging the long bar around the cross bar serving as the axis of rotation.

After the wire has been tensioned in this manner, the long bar is hooked to the wire by means of the hook provided at the end thereof, so that it will remain connected with the wire. A known device of this kind consequently can be used only once.

The present invention has reference to an improved device f! tensioning wires.

Therefore, according to the invention an end of a wire is passed through a hole or attached to a hook or some other means provided on a barshaped object and wound around the same with 25 the aid of a handle transversally arranged on the said bar, the bar being held against the post for the purpose of tensioning the wire; after this the bar is moved around the post, if necessary with a slight unwinding of the wire, until the tensioned portion of the wire is reached, whereupon finally the bar while the wire is being unwound is moved a few times around the tensioned portion of the Wire.

The wire tensioner briefly may be said to consist of a bar or a pipe which near the one end is provided with a handle, arranged transversely to the said bar and with a hole, a hook or a similar device located between the said handle and the other end of the bar and intended for attaching to the said bar the wire which is to be tensioned, whereas a hook is secured to the other end of the bar.

The accompanying drawing explains and illustrates the manner in which according to the invention a wire is tensioned with the aid of the tensioning device according to the said invention.

Figs. 1-4 of the said drawing are perspective illustrations of four consecutive stages of the tensioning process of a wire.

Figs. and 6 are perspective views of slightly modified forms of the device.

The wire tensioning device consists of a pipe I which near one end is provided with a hole 2, through which the end of the wire 3 which is to be tensioned, is passed in order to secure in this manner the wire 3 to the pipe l. Still closer to this same end, the pipe I is provided with a cross bar passed slidably through the said pipe I, which bar constitutes a handle with the aid of which the pipe I is to be turned about its centre line.

At the other end the pipe I is provided with a hook 5 the purpose of which will be explained hereinafter.

The wire tensioning device is operated as follows:

After the end of the wire 3 which is to be tensioned, e. g., for a fence, has been secured to the pipe l, the said pipe in the manner illustrated in Fig. 1 is held transversely against a fence post 6 and with the aid of the handle 4 is turned about its centre line, whereby the wire 3 is wound about the said pipe and tensioned.

If during this tensioning action the wire 3 should be held back by some obstacle, such as, e. g., a clump of grass, the pipe l is swung in a horizontal plane about the post 6 and is hooked fast to the wire 3 by means of its hook 5 (Fig. 2).

It will now be possible to unhand the wire tensioning device, in order to free the wire from its obstacle, without releasing the tension of the wire already obtained.

The tensioning of the wire is then continued in the manner described above, until the desired tension has been obtained. The pipe I is then swung about the post and is turned in the manner illustrated in Fig. 3 about the portion of the taut wire 3 which is directly adjacent to the post 6, whereby a portion of the wire wound on the pipe I is now wound around the taut wire 3. Finally the end of the wire is cut close to the pipe I, whereby the condition according to Fig. 4 is obtained and the tensioned wire 3 is secured to the post 6.

As a modification of the embodiment of the wire tensioning device described above, the handle 4 may also be constructed in some other manner, e. g., by tending the end of the pipe I at right angles to the said pipe as shown in Figs. 5 and 6, whilst the hole 2 for receiving the end of the wire to be tensioned may be replaced by some other device, e. g., a hook 2 for securing the wire end to the pipe I as shown in Fig. 5. The hook 5, as in the embodiment illustrated may be integral with the pipe l, but it may also be hooked fast in an opening provided in the pipe l or be connected with the pipe by means of a little chain or the like as shown in Fig. 6.

I claim:

A wire tensioning device comprising a bar, a handle at one end of the bar and positioned transversely thereof, a hook at the other end of the bar, and said bar between the said handle and the said hook and in the vicinity of the handle being provided with a means for facilitating the attachment to the said bar of the wire which is to be tensioned.
